Here’s a selection of mathematical news from the month of November that we didn’t otherwise mention on the site.

### Proof News

The dream team of Tim Gowers, Ben Green, Freddie Manners and Terence Tao (pictured above) claim to have solved the polynomial Freiman-Ruzsa conjecture (originally conjectured by Hungarian mathematician Katalin Marton), which is described by Gil Kalai in this blog post as ‘the holy grail of additive combinatorics’. *(via Terence Tao)*

It’s claimed that the board game Othello has been solved: according to this arXiv paper, perfect play leads to a draw. *(via Stephen Brooks)*

### Maths/politics

The UK Government has pledged “support to establish a National Academy focussed on mathematical sciences”. There has been a project to set up such an Academy as a recommendation from the Bond Review ‘The era of mathematics‘ in 2018, and it’s currently in a proto-setup phase.

Algorithmic trading firm XTX Markets has launched a $10m fund “designed to spur the creation of a publicly-shared AI model capable of winning a gold medal in the International Mathematical Olympiad”.

### And finally

Ben Orlin has released a few interactive online versions of games from his book “Math Games With Bad Drawings”.
